A fast and highly specific detection of COVID-19 infections is essential in managing the virus
dissemination networks. The most relevant technologies developed for SARS-CoV-2 …

Background SARS-CoV-2 is an enveloped, positive-sense single-stranded RNA virus with a
30-kilobase genome, which, like all viruses, accumulates nucleotide mutations over time …

SARS-CoV-2 variants of concern, demonstrating higher infection rate and lower vaccine
effectiveness as compared with the original virus, are important factors propelling the …

From early 2020, a high demand for SARS-CoV-2 tests was driven by several testing
indications, including asymptomatic cases, resulting in the massive roll-out of PCR assays to …

The race between pathogens and their hosts is a major evolutionary driver, where both
reshuffle their genomes to overcome and reorganize the defenses for infection, respectively …
